# Occurrence of Glioblastoma Five Years After Resection of Atypical Meningioma at the Same Anatomic Site: A Case Report

## TL;DR

A patient developed glioblastoma at the same site where an atypical meningioma was removed five years earlier, highlighting a rare occurrence.

## Contribution

This case report documents a rare instance of glioblastoma arising at the site of a previously resected atypical meningioma.

## Key findings

- A 54-year-old patient developed glioblastoma five years after resection of an atypical meningioma at the same site.
- The occurrence of glioblastoma at the site of a prior meningioma resection is extremely rare.

## Abstract

Atypical meningioma is a type of intermediate-grade meningioma (grade 2) according to the WHO classification. The occurrence of glioblastomas at the same site of resection of a meningioma is extremely rare and the causes of this type of mutations should be investigated. We present a case of a 54-year-old patient who five years after resection of a left parietooccipital atypical meningioma presented with a glioblastoma at the same site.
